thom FAULDERS: GEOtube is a proposal for a new 170 meter tall sculptural tower for the city of Dubai. With an open structure and an exposed membrane skin, the vertical planes of the GEOtube tower are continually misted with local salt water via an external vascular water system. The result is a uniform growth of salt crystals upon its highly visible surfaces. GEOtube provides an identifiable icon for the city, a specialized habitat for wildlife that thrives is this environment, and an accessible skin for the harvesting of crystal salt.
